The Digicell sim card is $50 BZ, and it includes $10 BZ of credit, and a new phone number.
It depends if your phone is unlocked or not, some might be locked to Telcel, in wish case you'll have to get it unlocked. Seaturtle might be able to unlock it for you, go check them out before you buy the sim, they'll be able to tell you.

Good Luck!
